It seems that your question is urgent. You posted two posts in a row around midnight, and I understand how you feel now. The information you introduced about yourself is also very honest. From their own growth experience, personality characteristics, and even when it comes to their vision after N years, it seems that they are really confused.
Needless to say, the construction industry is associated with the word "bitter and tired", and the bigger the construction unit, the greater the mobility, and it will come and go in the wind and rain all year round, with no fixed place to live. The employer and you are telling the truth, and there is nothing to hide. It's really bitter.
To tell the truth, unless there is a better background or way out, such as going to government departments or design units, construction companies are also an option, but the conditions cannot be compared with the former two. It is estimated that you may not be the person with this condition, at least you are not sure, otherwise you wouldn't be so upset.
However, the reality is that the superior conditions in your growth process will not easily reappear. In today's society, whether it is employment, work or the development and survival of enterprises, there is competition everywhere, especially in the current economic difficulties, this problem will become more prominent. You must be fully prepared, which anyone must face. Even if your parents, your school, is there no competition from lecturers or professors? You must overcome your personality weakness, cheer up, face difficulties and challenges bravely and fight for your future. There is no other way.
If you enter the construction unit, the most likely thing is to go to the construction site to exercise for a period of time, which is almost a stage that every graduate who has just joined the work in this industry has to go through. The job may be a technology, budget, information or builder. Although this stage is very bitter and tiring, it is necessary. No matter what kind of work you are engaged in in in the future, you need on-site practical work experience. There are many things on the construction site that you can't learn at school.
When you first arrive at the construction site, you should combine what you have learned in school, think more, learn more, ask more questions, and make clear the construction operation, technological process and working procedure arrangement, which is your capital and wealth for future development. Don't be afraid of jokes, just ask if you don't know how to get to school. Old construction workers also have to go through this process. As for the future development direction and results, it is possible to enter the department, engage in technology and design, be a project manager or an executive, depending on your own ideas and efforts.
Personal opinion, I don't know if it suits you. I hope it helps you. I wish you all your wishes.
